HOSE-COUPLING.

tPBCIFICATION forming part of Letters Patent No. 379,845. dated March20, 1888.

Application filed July 2l, 1887. Serial No. 244,923. (No model.)

To @ZZ wwm it may concern:

Be it known that I, CLARENCE W. BoLUss, a citizen of the United States,residing at Norwood, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Hose-Couplings; and l dodeclare the following to be a full, clear, and exact descriptionofthcinvention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention has relation to improvements in hose-couplings; and itconsists in the construction, novel arrangement, and adaptation ofdevices, as will be hereinafter more fully set forth and claimed.

ln the accompanying drawings, Figure l is a side elevation of myimprovements, showing the same coupling two sections of a hose. Fig. 2is a longitudinal central sectional view of the same, and Fig. 3 is anelevation of the parts disconnected.

Referring` by letter to the said drawings, A B indicate two sections ofa rubber or other suitable hose, and C indicates my improved couplingdevice. This coupling consists of the longitudinal centralbearing-tube,D, which has its opposite ends beveled exteriorly, as shownat a a, to receive the ends of the tube or hose, as will be presentlyexplained. This tube D is provided about midway of its length with asuitable number of integral fulcrumarms, b. Made i'astto the outer endsof these arms b, and preferably formed therewith, are compressibleclamps F. These clamps F terminate at opposite ends in curvilinearconical jaws d, which are threaded externally, as will be hereinafterdescribed. These jaws d are connected by an integral branch, e, whichhas its support upon the lugs b, the said branches having been reducedlongitudinally, as shown, so as to allow the same to give when the jawshave been compressed by rings, as will be presently described.

The ends ofthe bearing-tube D are extended slightly beyond the outeredges of the compressible jaws, so as to form a guide for theintroduction of the hose thereon and beneath the said jaws.

By reference to Fig. 3 of the drawings it will be seen that thecompressible jaws when expanded have an interspace between them, and thewhole comprise a clamp of conical annular form.

G indicates the compressingrings, there being one employed for eachconnected end of the hose. rlhe interiors of these rings are of conicalform and are threaded to engage the threads of the compressible jaws ofthe coupler. Thus it will be seen that when the ends of the hose havebeen adjusted upon the bearing-tube by turning up the conical rings uponthe jaws the same will be compressed and held forcibly against the saidbearing-tube, with the hose interposed, when a tightjoint will be formedand a connection of the parts effected. It should be observed that thetube, the compressible jaws, and their lug or stud supports may beformed in one piece,and these parts are preferably made of brass,although they may be made of other material. It will also be observedfrom the construction illustrated that there is nothing to get out oforder and that the parts are effective in their operation. It will alsobe Seen that by having the connections ofthe clamping-jaws long andnarrow there will be but litt-le resistance to the action of the ringsin compressing the said jaws upon the hose.

Having described this invention, what I claim isl. Thecompressibleclamping-jaws ofcurvilinear conical form, having externalthreads, and connected by the reduced portions supported on radial arms,and the bearing-tube formed with the said arms and havingits endsextended and beveled to form guides for the hose, in combination withthe internallythreaded conical compressing-rings, substantially asspecified. i

2. The bearing-tubehavingits ends beveled and formed with radial armsabout midway ofits length, and the compressible jaws connected byreduced parts supported on the said arms, substantially as specified.

In testimony whereof l affix my signature in presence of two witnesses.

CLARENCE V. BOLUSS.
